What is the Shimano 105 FC-R7000 34t chainring built for?

This is the 34 tooth inner chainring for the Shimano 105 FC-R7000 crankset, the small ring in a 50-34T compact road setup. It is the genuine Shimano replacement, machined from anodized aluminum in black to match the R7000 crank, so a worn or bent ring comes back to crisp, predictable front shifting without changing the feel of the drivetrain.

It mounts to the four-arm 110mm asymmetric bolt circle shared across the R7000 crank family and is the MS type, paired specifically for the 50-34T combination. Built for 11-speed road drivetrains, it is the right choice for riders refreshing a compact 105 crank or anyone who wants the easier climbing gear of a 34 tooth inner ring. Pair it with the matching 50t outer ring for a complete compact rebuild.
